Thank you so much for your post! I was almost freaked out when TT refused to e-file my NJ and NY returns. I not only restarted my computer, but also updated its BIOS. Also cleaned disc and system files. Turned off McAfee as well. All in vain. Couldn't even talk to a TT support because today is 4th of July! The whole morning I was helplessly stuck inside the endless loop! Then I found your post and clicked the TT Update Loop At e-file link. Although it only offers NY manual update file, hoping to solve NY problem first, I downloaded NY manual update. Unfortunately, my Windows Installer aborted installation due to some "program missing" or version mismatch. I moved the patch file to different locations on the disc but neither worked. Anyway, after went through many trials, I finally made it work. My solution is: disable McAfee, re-download state program, then clean disk and system files as you suggested, launch TT to make sure state update happens, e-file that particular state return. I've been using TT for 20 years, this is the first time it gave me such a big headache. Good luck to all TT users!
